This document is the Geo Spec 0801O. It explains the nonwoven geotextile specifications with filter fabric properties and physical properties tables.

This specification describes ADS 0801T/O nonwoven geotextile Filter Fabric Requirements. ADS 0801T/O is an orange nonwoven geotextile composed of polypropylene fibers, which are formed into a stable network such that the fibers retain their relative position. ADS 0801T/O is inert to biological degradation and resists naturally encountered chemicals, alkali and acids.

The filter fabric properties table explains property, test method, units and typical value MD, typical value CD of grab tensile strength, grab tensile elongation, trapezoid tear strength, CBR puncture strength, permittivity, flow rate and UV resistance after 500 hours.

The physical properties table lists property, test method, unit and typical value for weight, thickness, roll dimensions, roll area and estimated roll weight.

Notes state that apparent Opening Size (AOS): ASTM D4751: U.S. Sieve (mm): 60 (0.25) is tested to a Maximum Opening Diameter Value.
